Amazon held a tech-talk on campus, which I attended. Afterwards, there were recruiters collecting resumes. I gave the recruiter my resume and waited to hear back. I heard back about one month later, and scheduled an on-campus interview.
There were 3 back-to-back 45 minute interviews, which both involved coding with a pen and paper. During the first interview, we talked a bit about my resume, then got into some tech questions. Nothing too difficult, just practice what you learned in class. Bit-shifting and data structures, mostly. Also, KNOW YOUR TIME/SPACE COMPLEXITIES. Seriously. Before you offer a solution, know what its time/space complexity is, because they will ask for it. Lastly, there was a general logic question, which I didn't have time to answer, but I emailed the interviewer the answer later. Then, I was able to ask the interviewer some questions. The second interview wasn't very hard, just two slightly longer questions. The solutions weren't difficult, but they had a lot of corner cases that you needed to watch out for. Be very cognoscenti of that: If a question seems really easy, watch for corner cases. After that, same story, asked the interviewer some questions. Got the offer four days after the interview.
Some tips/notes:
1) Be yourself! Be friendly and nice. Don't be afraid to make a joke. Don't be awkward or nervous. Just relax. You've got this. It's very important to be well-spoken.
2) Know your time/space complexities.
3) Go over your data structures. Know them better than you know yourself.
4) Watch for corner cases.
5) If you slip up, just explain yourself and your mistake. They'll understand, we all do it.
6) Be VERY vocal about what you're thinking about. They care about how you arrive at the answer.
7) If they give you a question that you have heard before, tell them. They appreciate the honesty, and then you get a chance to talk a bit about the answer. I was given one question that I already knew the answer to, I simply told the interviewer that I was already familiar with this question, and gave him my solution. We talked about it, and then I was asked to come up with a different solution to the same problem.
8) Probably not something to stress about, but it probably helps to dress nice. Nothing amazing, I just wore a button-up and nice jeans. The point is, don't show up in a T-shirt and daisy dukes, or something. Dress like you care. You should care, after all.
9) If you've got an interview scheduled and you're reading this, like I was reading all of these before mine, you're probably stressing out like I was. Just calm down. Relax. Everything is going to be okay. You got the interview because they saw something in you. YOU'RE GOING TO DO FANTASTIC. I believe in you.
